Flexible FJ achbandleiti

The innovation can be seen on flexible Flaehbandleituagea mit several thin, flat and narrow strips of electrical, conductive material "wiping next to each other at a distance" layers of flexible insulating material, ζ · Β · synthetieehern Plastic material, lying and with a metal connector are provided "

Ribbon cables of this type are particularly popular in the electronics industry used when several with a relatively small distance next to each other connection contacts with the one Connection pieces η of different circuits are connected have to. So far you have the conductor strips of the ribbon cable

■ with the connecting pieces. characterized, in that they versohweißte through the insulation of the Flaohbandleitung or characterized in that the insulation were removed and the Leiterstseifen to the Ansohluiistüoken _o anlötete The compounds prepared in this manner between Flaehbandleitung and fittings jedooh nieht entirely satisfactory. One of the main difficulties in connecting by soldering is to remove the insulation from the thin conductor strips in such a way that none of these delicate conductor strips is damaged.

With the new flexible flaehband cable with between two Insulating layers and conductors lying next to each other at a distance · « strips fitted with metal fittings, these sewn parts are avoided Longitudinal edge of the conductor strips, the insulating layers are removed and that the exposed longitudinal edges of the conductor strips electrically conductively connected to the separate connection pieces are ·

This improved type of connection between Flaehbandleitung and Ansohlußstüoken is achieved above all that the Isoliersohiohten in the area of the connecting pieces between the his ladder strelfen are cut out and that the ladder strips la longitudinal direction of the flaoh tape line protruding and on two opposite, flat sides with an insulating layer provided fingers · Each of the fingers made up of a conductor strip and two insulating layers can be attached be attached to the associated Ansehlußstüek that at least an exposed longitudinal edge of each conductor strip the connection stuok is electrically connected to a safe Contact is then reached when, when the between the part of the insulating strip lying on the conductor strip the ladders along at least one long edge became.

As shown in the drawing, a ribbon cable comprises several thin »flat and sehmal strips a made of electrically conductive material · The strips a can be made of copper or a suitable made of another metal · They are spaced apart and are sandwiohartig between flexible sole plates b »ο made of insulating material» e.g. a plastic »arranged.

The Flaohbandleitung shown is for attaching connecting pieces ρ made of metal · For this purpose, the Absohnte d removed between adjacent ladder stripes

After this stripping process, the flaoh tape line remains in the longitudinal direction there are protruding fingers e, each containing a conductor strip a «Take care when stripping» that at least one longitudinal edge of each strip is exposed will·

Vie Fig «2 aeigt, is when stripping» for example by. Cut or punch out, not only will the insulation between the conductor strips be removed, but the lengthwise edge will also be removed the stripe trimmed, ao that the fingers a in the cross-son are slightly narrower than the conductor strips in the main part of the flaoh tape that has not been processed.

As can be seen in particular from FIGS. K and 5, each finger rests on a metal piece ρ and overlaps it a little. The finger e can be twisted a little for sufficient overlap. The finger is then attached to the connector by wrapping wire around it, the wire wrapping around the finger and connector with the Drahtumwieklung and these in turn are electrically connected to the Ansohlußstüok.

In this way, all of the fittings are »for example Steek pens or cans, by wrapping one around Wire 1 connected to the Ansohlußstücke.

By stripping the insulation when cutting or punching out the insulation between all conductor strips of the flaoh tape line can be removed at the same time · if only a specific one Number of conductor strips to be connected to connection sticks should, it is sufficient »simply the isolation between these lines» remove streaks

It is an advantage if both longitudinal edges are rolled off of a ladder strip can be uncovered · In some cases, however, it is sufficient if only one longitudinal edge of a conductor ·· Strip is exposed

For example, bare, tinned copper wire can be used to wrap the connector and finger

ti t

Wrapping can be done in any way and with any tool · Each finger is attached to its connector fixed by wrapping a special piece of wire

By wrapping it with wire, the insulation is cut at the edges of the fingers, creating a multi-point electrical connection arises.

Because the two flat sides of the ladder strelfen in the fingers ▼ on Xsolation are covered »are the fingers when attaching it the connection pieces clay worn these top layers · Da in addition the first turns of the wire winding that "tend" to give in a little, make a special strain relief unnecessary each junction

The new connection between Ton Flaehbandleitung and AnsehluAstüeken from Netall offers the advantage * that stripping with a simple tools and that there · wrap around with wire old with the help of a common wirewinder Can · In addition, both the Head Sound Flashbandle as well as normal wire lines Connect Ansohlußstüeken and if necessary you can at each attach more than one ladder strip to any connection piece

Removing the insulation from the flat sides of the conductor strips a Flaehbandleitung is no longer required height and the connections with the connection pieces can be made on site and Body can be manufactured without complicated machines, tools or processes.
